Digital Transmitter
TFP410 is a digital transmitter which transmits LCD signals to the HDMI port. The DVI
power down signal is connected to the active-low power down pin (PD) of the
transmitter. The TFP410 transmits three pairs of differential signal outputs and one pair
of differential output clock to the HDMI connector. The EDID I2C signals that goes to
the HDMI connector is at 5V; thus, a 2-bit bi-directional voltage translator
TXS0102DCU is required to step up the EDID I2C signals from main expansion header
P2 to 5V. Figure 5 shows the TFP410 and TXS0102DCU in the schematic.
